ToaZZ whom it may concern:

Be it known that 1, ANDREW couver, in the Province of British Golum bla,Canada, have lnvented certaln new and useful Improvements inWVire-Rope'lrans' mission Carriages, of which the following is aspeclfication. H i

This inventlon relates to the carrier of a wire rope transmission systemof that class wherein the load is suspended from a car-- riage which ismovable along an overhead stationary track rope and is drawn along it bya moving wire rope. With this system the suspendedload is carried pasttheguy ropes or supports which sustain the track rope by a pair of starwheels havinglateral projections from the arms of the star, from whichprojections the load is suspended. hen a guy rope or track supportisencountered by the arms of the star wheels,

j the star wheel rotates to pass the carriage a tween the arms of thestar wheel.

over it while the load is sustained fromuthe. lateral projections of thestar wheel arms With this device, the hauling rope requires to beconnected to that portion of the carriage which is above the track ropesupports and this hauling rope moving over the sup porting guy ropes isdestructive of them: Further, as the arms of the star wheels engage thetrack supports the momentary check causes the load to swing and thisswinging movement carries the star wheels with it and frequentlyinterferes with the free entrance of the track rope supports be- It isto overcome these objections that the invention, which is the subject ofthis application, has been devised: In it, instead of using one pair ofstar wheels on the track carriage, the carriage is supported on two ormore rollers, each having a star wheel on each side of it, and suspendedfrom the lateral projections of these two pair of star wheels is anundertrack frame, from the middle of which the load is pivotallysuspended. With thisar- I rangement the hauling rope is connected to theunder-track part of the carriage, and the load may swing freely on itspivotal connection thereto without disturbing the carriage orinterfering with the free action of the star wheel arms. The load isalso halved in the amount which is carried by the lateral projections ofthe star wheels enabling them to rotate more easily.

The invention is particularly described in Specification of LettersPatent.

WIRE-RQPE-TRANSMISSION CARRIAGE. 3

Patented Aug. 11, 19M.

Application filed May 21, 1914. Serial No. 840,057;

the following specification, reference being made to the drawings bywhich it is accompanied, in which: i i 1 Figure 1 is a longitudinalsection. Fig. 2, a plan, and Fig. 3, a cross section on the line A inFig. 1.

In these drawings 2 represents the wire rope track and 3 the supportsbywhich it is sustained. These supports 3 are generally connected in wireropes which are stretched across beneath the line of the track ropebetween adjacent trees, or between posts or towers where trees are notavailable. The

, carriage by which the load is conveyed along 121118 track rope 2comprises an over-track frame 4 composed of two elongated side plateshaving between them at each end two or more roller wheels 5, each rollerwheel having a star wheel 6 at each endof it which is independentlyrotatable on the pin7 of The radial arms-of these star wheels 6 haveshouldered projections 8 which are concentric, with the pin on whichitrotates. From these shouldered projections 8 an under-track frame 10is carried, which underframe is constructed of two lengthwise plates,each having inside its upper edge an inwardlyprojecting shoe 11 which iscurved to the arc of the shouldered projection 8 of the star wheel fromwhich it is carried.

The attachment 14: from which the load is carried is pivotally connectedat 12, and the hauling wire rope 13 by which the carriage is moved alongthe track rope is connected at 15 to each end of the under-track frame10.

The hauling rope 13 being connected to the under-track frame of thecarriage cannot wear the track rope supports and the load beingpivotally connected to the under frame and its weight carried by two ormore pair of star wheels, oscillation of the load does not disturb thecarriage or interfere with the free action of the arms of the starwheels in passing over the track rope supa new anddesire to be protectedin by Letters Patent, is:

, 1. A carriage for an overhead transmission system, said carriagecomprising an upper frame having a plurality of roller wheels which bearupon the track rope, each roller wheel having a star wheel on each" sideof it, each star wheel having outwardly projecting shoulderedprojections which are concentric with the axis of its roller wheel,

and an-under-track carriage Supported from the shouldered projections ofthe star wheels and including two side plates, each having projectionsto cooperate with thcprojections of the'star wheel.

2. A track rope carriage for an overhead transmission system, comprisingan upper carriage supported from the track rope on a plurality ofrollers, eachhaving a star Wheel on each side ofit which is independventlyrotatable on the pin of its roller wheel,

c5 11 of this patentmay be obtained each of said star wheels havingoutwardly; projected shouldered projections from its radialarms, theshouldered faces ofrwhich are concentric with the axis of its roller.wheel, an under-trackcarrlage comprising a-palr ofslde plate havinglnward pro ections to engage the shouldered projections of the starwheels, and means for pivotally connecting the load to this undercarriage.
